Issues with High Sierra on E7440


Recommended Posts

Hello folks, I was able to successfully install Sierra High by using Jake's Clover Guide (thank you). https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-clover-guide/&do=findComment&comment=54621


I need help in following issues:


1. The Mac Would go to sleep if I invoke the sleep by going to the start menu. However running on power or when I close the lid it keeps running.


2. And secondly after I boot the display is garbled until I let it sit for 20 minutes or so and then it changes to a functional display and works great until I do a reboot. Enabling Legacy Boot in the BIOS would not let it boot. 


Here is the output of assertions!

Idle sleep preventers: IODisplayWrangler (Is this causing it?)





Please suggest any troubleshooting ideas.

Its working...


Were you using a patched AppleHDA or the one included in the bootpack by Jake (https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-clover-guide/&do=findComment&comment=54621). AppleHDA_ALC292 needs to go in the LE folder.


Also the boot-pack also has plist with AHDA patches. 


I hope this helps.

Jake thanks for getting back and providing an update. after serval reboots and permission repairs, once executed successfully, there is no garbled screen anymore. 


However, I am having issues with PM. Currently using clover 4220 as updated by RehabMan few days ago. The fan keeps running high all the times before and after the cover update.  


I found following text interesting, can you please shed more light on it. eg do we still need to generated a ssdt as its in the guide or do smth different as explained by ReHab Man.


Thanks (https://github.com/RehabMan/Clover)

  • allow finer control over ACPI/SSDT/Generate/PStates with addition of Generate/APSN, Generate/APLF, Generate/PluginType options. So, with Haswell or later, you can enable CPU PM with only config.plist/ACPI/SSDT/Generate/PluginType=true.

  • And with Sandy or Ivy, for use with SSDT.aml generated from ssdtPRgen.sh, but you need to drop the OEM tables and use Generate=true, you can disable APLF/APSN generation with Generate/PStates=true, Generate/CStates=true, Generate/APLF=false, Generate/APSN=false.

  • The new settings are backward compatible with old config.plist files (no change in behavior when the new options are missing, all new options are default true). Note that because APSN/APLF are part of Generate/PStates, they have no effect unless Generate/PStates=true, whereas PluginType is independent, and is effective regardless of Generate/PStates selection.
